♠ I-INA281-Q1 AEC-Q100, -4-V ukuya ku-110-V, 1.3-MHz I-Current-Sense Amplifier
I-INA281-Q1 iyisikhulisamazwi samanje sokunemba okuphezulu esikwazi ukukala ukwehla kwamandla kagesi kuzo zonke izimbangi ze-shunt phezu kwebanga elibanzi lemodi evamile ukusuka ku- -4 V ukuya ku-110 V. Ivoltheji yemodi evamile engalungile ivumela idivayisi ukuthi isebenze ngaphansi komhlabathi, ngaleyo ndlela ivumelane nesilinganiso esinembile sokujikeleza kwemisinga kuzinhlelo zokusebenza zebhuloho elinguhhafu. Inhlanganisela ye-voltage ephansi ye-offset, iphutha elincane lokuzuza kanye ne-DC CMRR ephezulu inika amandla ukukalwa kwamanje okunembe kakhulu. I-INA281-Q1 ayakhelwe nje kuphela ukulinganisa kwamanje kwe-DC, kodwa futhi nezinhlelo zokusebenza ezinesivinini esikhulu (njengokuvikelwa kwe-overcurrent esheshayo, isibonelo) enomkhawulokudonsa ophezulu ongu-1.3 MHz kanye ne-65-dB AC CMRR (ku-50 kHz).
I-INA281-Q1 isebenza kusukela kokunikezwayo okukodwa okungu-2.7-V kuya ku-20-V, idonsa u-1.5 mA wokunikezwa kwamandla. I-INA281-Q1 iyatholakala ngezinketho ezinhlanu zokuzuza: 20 V/V, 50 V/V, 100 V/V, 200 V/V, kanye ne-500 V/V. Lezi zinketho zokuzuza zikhuluma nobubanzi obuguquguqukayo obubanzi bezinhlelo zokusebenza zenzwa yamanje.
I-INA281-Q1 icaciswe ebangeni lokushisa lokusebenza elingu-−40 °C kuya ku-+125 °C futhi inikezwa ngephakheji ye-SOT-23 esindisa isikhala enezinto ezimbili ezihlukene zokuphina.
